Technoscope for determining the extent of damage to an object

Abstract

A technoscope for determining the extent of damage to objects includes an endoscope which is displaceable with a fixed stroke in a guide with a point of the object being coincided with a scale at both terminal positions of the stroke, the scale being in the form of a transparent screen plate which is displaceable transversely of the axis of the endoscope, a first measurement value transmitter for mechanically detecting the displacement value of the endoscope and for converting the same into an electrical signal being connected to a calculator, and a distal prism for lateral viewing being pivotally displaceable in the endoscope with the angle of pivotal displacement being mechanically detected and converted into an electrical signal which is transmitted to the calculator.

What is claimed is: 
     
       1. In a technoscope for determining the extent of damage to an object and including an endoscope having a proximal ocular, a distal prism for lateral viewing, and being displaceable axially by a fixed stroke in a guide which can be fixed with respect to the object, and a scale for coinciding with a point of the object and being observable through the ocular in both terminal positions of the endoscope stroke, the improvement which comprises: a transparent screen plate which incorporates said scale and which is displaceable transversely of the endoscope axis by means of a micrometer screw which is operable from outside the endoscope, a first measurement value transmitter for mechanically detecting the displacement value of the endoscope and for converting the said displacement value into an electrical signal which is fed to a calculator to calculate the object distance, means for pivotally displacing said distal prism, and a second measurement value transmitter for mechanically detecting the pivotal displacement value of said distal prism and for converting the pivotal displacement value into an electrical signal which is fed to the calculator to calculate the extent of the damage.   
     
     
       2. A technoscope as claimed in claim 1, wherein the calculator includes an evaluator unit through which the electrical signals are fed.
